Regarding blind defense in 6max

[Alex/Mugaaz]

I see a lot of posts regarding this, but I can't help but think that anything said about it is pretty much worthless if you don't take the rake structure into account as well as the blind structure (especially if you aren't playing the upper limit games online). How can any comments be worthwhile if they don't consider this? I'm trying to learn this aspect of play ATM but everything I read feels like it will simply lead to fundamental errors later.

Has anyone developed some sort of graph that accurately shows where cutoff points for your call/bet/raise points vs certain hand ranges change based on the rake and blind structure? Or is everyone simply winging it?
